Optical assembly comprising a conical mirror

An optical assembly is disclosed. The optical assembly includes a collimating lens which collimates a divergent laser beam. A conical mirror has a reflecting cover surface and deforms a laser beam, which propagates in the direction of the conical axis, into an annular beam in a propagation plane perpendicular to the conical axis. An optics carrier has a first carrier element on which the collimating lens is fixed and a second carrier element on which the conical mirror is fixed. A connection device has at least one connection element which connects the first and second carrier elements to one another. The at least one connection element is arranged askew to the conical axis of the conical mirror.
